COPY-HOLDER FOR TYPE-WRITERS.

SPECIFICATION forming part of Letters Patent No. 469,658, dated February23, 1892. Application filed February 24, 1891. Serial No. 382,385- (Nomodel.)

.To all whom, it may concern:

Be it known that I, STANLEY LINUS CHAP- lvIAN, of Evanston, Cook county,Illinois, have lnvented certain new and useful Improvements inCopy-Holders, of which the following 1s a full, clear, and exactdescription, reference being had to the accompanying drawings, and tothe letters of reference marked thereon.

My invention relates more particularly to a copy-holder fortype-Writers, although it may be used by others wherever the holding ofa copy and the indicating of the place thereon is necessary.

The object of my invention is to enable the copylst or type-Writer toreadily mark or indicate the exact place or line to which his attentionis necessary as he copies the same from top to bottom, and which is soconstructed that the distance the marker travels each time it is movedto indicate the next following line of matter can be regulated so as tocorrespond to the distance between the lines of the copy, substantiallyas hereinafter fully described, and as illustrated in the drawings, inwhich Figure 1. is a side elevation of my invention. Fig. 2 is a frontelevation of the same. Fig. 3 is a transverse horizontal section of mylmproved copy-holder, taken just above the plane of the rule-barthereof. Fig. 4 is a side elevation of a modified form of my invention,and Fig. 5 is a front elevation of the modification shown in Fig. 4.

In the drawings, A represents a suitable base having suitable legs, thespread of which 1s sufficient to maintain the equilibrium of thecopy-holder under ordinary usage, and a central post arising from thebase which is provided with a central bore with a set-screw a tappedlaterally into it near the upper end of the post. Entering the bore ofthe post from above is a spindle of corresponding diameter, which can beadjusted at any desired elevation consistent with its length by means ofthe said set-screw a. The upper end of the spindle B is provided with ahead which is of greater diameter and is divided longitudinally andcentrally from its upper end,

so as to provide suitable lugs, near the upper extremities of which thequadrant 12, secured to the back of the plate C, is pivoted. The pointat which said quadrant is pivotally connected to the head of the spindleB corresponds to the center from whence said quadrant is struck. Inorder to hold said plate at any angle, all that is necessary is toincline the same thereto, and then by tightening-a suitable set-screw c,tapped laterally into the side of the head of the spindle and bearingagainst the side of the said quadrant, secure the same rigidly in suchinclined position. I do not wish, however, to be considered as claimingas original with me the features of my copy-holder thus far described,as such construction is the one ordinarily employed in all copy-holdersnow in common use.

At the top and preferably at about the center of Width of plate C, Iprovide it with a suit-able clasp or clamp D for securing the copy inposition, so that the lines of printed or written matter thereon will behorizontal. This clamp may consist of a simple springactuated plate ordog journaled between suitable lugs connected to and arising from saidplate, so as to hold the copy thereon, as shown. As there are manyclamps which are used for this purpose, I do not wish to be confined toany particular kind.

Arising from preferably the upper and lower left-hand corner of theplateCare suitable lngs d d, which have secured vertically between themand parallel to the left-hand edge of said plate the tube E, which isprovided with a longitudinal slot 6 on its outer side, which extendsfrom within a half-inch, say, of the upper lug to within about the samedistance of the lower lug (Z. Passing longitudinally through this tubeis a bar F, which has its side oppositethe slot 6 serrated. Theseserrations may be made by screwthreading the said bar or by simplyproviding its surface next said slotewith the serrations f, as shown.This bar extends through the said lugs 61 and is given a reciprocatingmotion by means of a lever G, which is fulcrumed at or near its centerof length to or between suitable lugs extending from or con- 1 nected tothe lower edge of plate C or otherwise. The position of this lever G ispreferloo ably parallel with the lower edge of the plate, with its endfarthest from the said bar so constructed as to provide amplesurface forthe finger to be pressed down thereon. The other end of the said leveris bifurcated and passes to either side of the neck of a suitable head 9on the lower end of the bar F. Said lever, when the finger is presseddown upon its free end, is restored to its normal position immediatelyafter by means of a spring h pressing down upon the end thereof adjacentto the bar. This spring may be either a flat spring, as shown,or acoil-spring. This same result, however-namely, that of restoring thesaid lever, and consequently the bar-could be accomplished equally wellby a coil expansion-spring surrounding said bar F and interposed betweenthe lower lug d and the head thereof.

It is desirable, as will hereinafter be more fully explained, that thebar F should be capable of making reciprocations of various lengths bymeans easily controlled by the operator. These means consist simply of anut H on the upper screw-threaded end i of the bar F, extending abovethe upper lug (Z. By adjusting this nut II the reciprocations of the barcan be easily regulated. In order that it may not be necessary for thethreaded part of the bar to pass through the upper lug when making itsreciprocations, however, I provide the under surface of the nut with adepending arm 75, which is parallel with the bar, and the lower end ofwhich always bears upon the upper surface of the lug (i. As is apparent,the substitution of this arm avoids the necessity of the screw-threadedend i of the bar passing through the guide-opening in the lug andpossibly interfering with the ready reciprocation of the bar.

Snrroundin g the tube E-is a carrier K,which consists, preferably, of acasting having a horizontal vertical opening made there: through, so asto enable it to surround the tube, and having lips m, caused by slottingthe casting transversely into said opening. By bringing these two lipstogether by means of a suitable screw n I am able to make the carriersurround and hug said tube more tightly, so as to overcome any variationbetween the diameter of the said tube and the opening in the carrier, asoccasion may require.

Passing transversely and at right angles to the back of the tube Ethrough the carrier (which is suitably proportioned for this purpose) isthe transverse rule-bar I. This bar may be so constructed as to mark thelines of the copy itself; but in view of the difierent thicknesses ofcopy which it might from time to time be desirable to put on my holder,Iprefer to connect thereto, by means of suitable links or arms 0 0, theparallel rule J. On the end of the rule-bar extending from the left-handside of the carrier I put a set-nut L, by tightening which, after I haveturned the bar I so that the rule J can rest against the copy, I cansecure said bar I in any position to which it may be adjusted.

Secured to the outer surface of the carrier K is a pawl M. This pawlextends longitudinally beyond the upper end. of the carrier and has itsfree end turned inward, so that it passes through the slot e of the tubeE and engages the serrations of bar F. TlllS pawl is made of suitablespring or flexible metal, and it engages the serrations of the bar F atsuch an angle that when said bar is pushed upward it rides over saidserrations; but when said bar returns to its normal position theopposing shoulder of the set-ration which it enters pushes against it soas to carry it and the carrier K downward the full extent of thedownward movement of the said bar. In order to move the carrier to thetop of plate 0, so as to permit the rule Jto indicate the line of thecopy from top to bottom thereof, it is necessary to'lift the point ofthe pawl out of engagement with the serrationsot thebarF.Thiscouldbedoneinasomewhat clumsy manner by catching the point of theflexible pawl, pulling it outward, and at the same time drawingthecarrier upward to the top of the tube, where, upon releasing thepawl, it would engage the said serrations and hold the carrier at thetop untilthe same was worked downward again through the reciprocationsof the bar. I prefer, however, to bend the end of the said pawl outwardfrom the point which engages the said serrations so as to form a spur N,which can be easily grasped by the fingers to lift the point of the pawlout of engagemeht with said serrations. If desired, a stop-post 0 couldbe secured to and project out from the carrier, which would prevent thispawl from being bent outward too far and prevent the possibility of itsbeing broken or permanently bent so that it would not engage saidserrations.

It is obvious that my improvements could be applied to the right-handside of the plate by simply constructing the several devices I havedescribed with a view to making the rule-bar I and the rule J extend tothe left of the carrier instead of to the right, as shown. I prefer thelocation hereinbefore described and shown, however, it being the mostnatu ral one.

If desired, the lever G could be dispensed with altogether and the lowerend of bar F provided with such a construction that it could be readilygrasped and drawn downward. It would make no difierence, so far as theaction of the bar F on the pawl is concerned, whether itsinitialmovement was upward or downward. In this event, however, I would place acoil-spring around the upper end of the said bar projecting above lug dand between the same and the nut on the upper end of said bar, so as torestore the bar automatically to its original position again.

In Fig. 4 I have shown a modification of my invention so far as the tubeE is concerned. The said tube is dispensed with altogether, and insteadI provide two parallel rods 0 r, which are placed one on each side ofthe reciprocal bar F and preferably an equal distance therefrom andwhich connect and are connected at their ends to the lugs d d. Theconstruction and operation of the bar F are the same as hereinbeforedescribed; but the carrier is so constructed that the bars passlongitudinally through knuckles proj ecting on either side of the bar.Otherwise the carrier is the same as has been hereinbefore described.
